When at least one lens among the second to the sixth lenses has weak positive refractive power, it may share the positive refractive power of the first lens, and on the contrary, when at least one lens among the second to the sixth lenses has weak negative refractive power, it may fine turn and correct the aberration of the system.

In an embodiment, the seventh lens could have negative refractive power, and an image-side surface thereof is concave, it may reduce back focal length and size. Besides, the seventh lens can have at least an inflection point on at least a surface thereof, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

In the optical image capturing system, the lenses could be made of plastic or glass. The plastic lenses may reduce the weight and lower the cost of the system, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the system. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that can obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the system.

When the lens has a convex surface, which means that the surface is convex around a position, through which the optical axis passes, and when the lens has a concave surface, which means that the surface is concave around a position, through which the optical axis passes.

The optical image capturing system of the present invention could be applied in a dynamic focusing optical system. It is superior in the correction of aberration and high imaging quality so that it could be allied in lots of fields.

The optical image capturing system of the present invention could further include a driving module to meet different demands, wherein the driving module can be coupled with the lenses to move the lenses. The driving module can be a voice coil motor (VCM), which is used to move the lens for focusing, or can be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.

To meet different requirements, at least one lens among the first lens to the seventh lens of the optical image capturing system of the present invention can be a light filter, which filters out light of wavelength shorter than 500 nm. Such effect can be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

Seventh Embodiment

As shown in FIG. 7A and FIG. 7B, an optical image capturing system of the seventh embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 710, a second lens 720, a third lens 730, an aperture 700, a fourth lens 740, a fifth lens 750, a seventh lens 760, a seventh lens 770, an infrared rays filter 780, an image plane 790, and an image sensor 792. FIG. 7C is a transverse aberration diagram at 0.7 field of view of the seventh embodiment of the present application.

The first lens 710 has negative refractive power and is made of glass. An object-side surface 712, which faces the object side, is a convex surface, and an image-side surface 714, which faces the image side, is a concave surface.

The second lens 720 has negative refractive power and is made of glass. An object-side surface 722 thereof, which faces the object side, is a concave surface, and an image-side surface 724 thereof, which faces the image side, is a concave surface.

The third lens 730 has positive refractive power and is made of glass. An object-side surface 732, which faces the object side, is a convex surface, and an image-side surface 734, which faces the image side, is a convex surface.

The fourth lens 740 has positive refractive power and is made of glass. An object-side surface 742, which faces the object side, is a convex surface, and an image-side surface 744, which faces the image side, is a convex surface.

The sixth lens 760 can have positive refractive power and is made of glass. An object-side surface 762, which faces the object side, is a concave surface, and an image-side surface 764, which faces the image side, is a convex surface.

In the seventh embodiment, the optical image capturing system of the seventh embodiment further satisfies ΣPP=58.2236 mm; and f3/ΣPP=0.1720, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the seventh embodiment further satisfies ΣNP=−33.2827 mm; and f1/ΣNP=0.2545, where ΣNP is a sum of the focal lengths of each negative lens.
